The PWTM65 series energy-saving casement door system is a high-end energy-saving casement door system developed by our company based on European advanced technology and design concepts in response to the needs of the Chinese door and window market. It is mainly suitable for areas with permeability and moisture resistance requirements, such as balconies. Doors, kitchen doors, toilet doors and corridor doors. Its excellent safety performance, physical properties, thermal insulation performance and humanized opening method have been recognized by the majority of users.
The system can choose the corresponding internal and external casement forms according to the functional requirements, and can be made into a variety of forms and styles such as single leaf, double leaf, and door window.
The system has a scientific and reasonable cross-section structure, standardized supporting hardware accessories, mature and standardized processing and construction technology, which can well guarantee the quality and performance of the product.
1. Insulation performance: Insulating glass is configured according to the standard （6 + 12A + 6Low-E）. The overall insulation performance can reach level 5, that is, 3.0> K≥2.5W / （m2? K）, and the configuration can be adjusted up to 5 according to demand. Above.
2. Wind pressure resistance: rigid design meets different load requirements. The wind pressure resistance can reach more than 9 （P≥5.0KPa）.
3. Water-tight performance: a reasonable drainage water channel is provided, which is combined with dredging and blocking. Watertight performance can reach level 5 （500≤ △ P ＜ 700Pa）.
4. Air-tight performance: Reasonable structural design and high-quality sealing materials ensure the integrity of the seal. The air-tight performance can reach level 7 （the index value of unit seam grading index 1.0≥q1 ＞ 0.5 m3 / （m? H） or Area classification index value 3.0≥q2 ＞ 1.5m3 / （m2? H））.
5. Sound insulation performance: up to level 3 （30≤Rw + Ctr ＜ 35dB）.
6. Hardware accessories: adopt standard European standard hardware notches, which can be matched with many brand hardware.
7. Profile: The design wall thickness of all the main members is 2.0mm.
